Spring OAuth2 授权服务器配置详解

前两篇文章分别体验了Spring Authorization Server的使用和讲解了其各个过滤器的作用。今天来讲讲Spring Authorization Server授权服务器的配置。强烈建议自己手动搭建一次试试，纸上得来终觉浅，深知此事要躬行。提升你的代码量才是提高编程技能的不二法门，这也是本篇教程的意义所在。同时也希望多多点赞，转发，多多支持作者原创分享。

配置依赖

首先要创建一个Spring Boot Servlet Web项目，这个不难就不赘述了。集成Spring Authorization Server需要引入：

<!--  spring security starter 必须  --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId></dependency><dependency><groupId>org.springframework.security</groupId><artifactId>spring-security-oauth2-authorization-server</artifactId><!--  截至现在版本  --><version>0.2.0</version></dependency>

OAuth2.0 Client客户端需要注册到授权服务器并持久化，Spring Authorization Server提供了JDBC实现，参见JdbcRegisteredClientRepository。为了演示方便这里我采用了H2数据库，需要以下依赖：

<!--  jdbc 必须引入否则自行实现  --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jdbc</artifactId></dependency><dependency><groupId>com.h2database</groupId><artifactId>h2</artifactId></dependency>

❝

生产你可以切换到其它关系型数据库，数据库脚本在Spring Authorization Server入门一文的DEMO中。

Spring Authorization Server配置

接下来是Spring Authorization Server的配置。

过滤器链配置

根据上一文对过滤器链的拆解，我们需要在Spring Security的过滤器链中注入一些特定的过滤器。这些过滤器的配置由OAuth2AuthorizationServerConfigurer<HttpSecurity>来完成。以下为默认的配置：

void defaultOAuth2AuthorizationServerConfigurer(HttpSecurity http) throws Exception {OAuth2AuthorizationServerConfigurer<HttpSecurity> authorizationServerConfigurer =new OAuth2AuthorizationServerConfigurer<>();// TODO 你可以根据需求对authorizationServerConfigurer进行一些个性化配置RequestMatcher authorizationServerEndpointsMatcher = authorizationServerConfigurer.getEndpointsMatcher();// 拦截 授权服务器相关的请求端点http.requestMatcher(authorizationServerEndpointsMatcher).authorizeRequests().anyRequest().authenticated().and()// 忽略掉相关端点的csrf.csrf(csrf -> csrf.ignoringRequestMatchers(authorizationServerEndpointsMatcher))// 开启form登录.formLogin().and()// 应用 授权服务器的配置.apply(authorizationServerConfigurer);}

❝

你可以调用OAuth2AuthorizationServerConfigurer<HttpSecurity>提供的配置方法进行一些个性化配置。

OAuth2.0客户端信息持久化

这些信息会持久化到数据库，Spring Authorization Server提供了三个DDL脚本。在入门教程的DEMO，H2会自动初始化执行这些DDL脚本，如果你切换到Mysql等数据库，可能需要你自行执行。

客户端配置信息注册

授权服务器要求客户端必须是已经注册的，避免非法的客户端发起授权申请。就像你平常去一些开放平台申请一个ClientID和Secret。下面是定义脚本:

CREATE TABLE oauth2_registered_client
(id                            varchar(100)                        NOT NULL,client_id                     varchar(100)                        NOT NULL,client_id_issued_at           timestamp DEFAULT CURRENT_TIMESTAMP NOT NULL,client_secret                 varchar(200)                        NULL,client_secret_expires_at      timestamp                           NULL,client_name                   varchar(200)                        NOT NULL,client_authentication_methods varchar(1000)                       NOT NULL,authorization_grant_types     varchar(1000)                       NOT NULL,redirect_uris                 varchar(1000)                       NULL,scopes                        varchar(1000)                       NOT NULL,client_settings               varchar(2000)                       NOT NULL,token_settings                varchar(2000)                       NOT NULL,PRIMARY KEY (id)
);

对应的Java类为RegisteredClient:

public class RegisteredClient implements Serializable {private static final long serialVersionUID = Version.SERIAL_VERSION_UID;private String id;private String clientId;private Instant clientIdIssuedAt;private String clientSecret;private Instant clientSecretExpiresAt;private String clientName;private Set<ClientAuthenticationMethod> clientAuthenticationMethods;private Set<AuthorizationGrantType> authorizationGrantTypes;private Set<String> redirectUris;private Set<String> scopes;private ClientSettings clientSettings;private TokenSettings tokenSettings;// 省略
}

定义一个客户端可以通过下面的Builder方法实现：

RegisteredClient registeredClient = RegisteredClient.withId(UUID.randomUUID().toString())
//               唯一的客户端ID和密码.clientId("felord-client").clientSecret("secret")
//                名称 可不定义.clientName("felord")
//                授权方法.clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
//                授权类型.authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE).authorizationGrantType(AuthorizationGrantType.REFRESH_TOKEN).authorizationGrantType(AuthorizationGrantType.CLIENT_CREDENTIALS)
//                回调地址名单，不在此列将被拒绝 而且只能使用IP或者域名  不能使用 localhost.redirectUri("http://127.0.0.1:8080/login/oauth2/code/felord-oidc").redirectUri("http://127.0.0.1:8080/authorized").redirectUri("http://127.0.0.1:8080/foo/bar").redirectUri("https://baidu.com")
//                OIDC支持.scope(OidcScopes.OPENID)
//                其它Scope.scope("message.read").scope("message.write")
//                JWT的配置项 包括TTL  是否复用refreshToken等等.tokenSettings(TokenSettings.builder().build())
//                配置客户端相关的配置项，包括验证密钥或者 是否需要授权页面.clientSettings(ClientSettings.builder().requireAuthorizationConsent(true).build()).build();

持久化到数据库的RegisteredClient用JSON表示为：

{"id": "658cd010-4d8c-4824-a8c7-a86b642299af","client_id": "felord-client","client_id_issued_at": "2021-11-11 18:01:09","client_secret": "{bcrypt}$2a$10$XKZ8iUckDcdQWnqw682zV.DVyGuov8Sywx1KyAn4tySsw.Jtltg0.","client_secret_expires_at": null,"client_name": "felord","client_authentication_methods": "client_secret_basic","authorization_grant_types": "refresh_token,client_credentials,authorization_code","redirect_uris": "http://127.0.0.1:8080/foo/bar,http://127.0.0.1:8080/authorized,http://127.0.0.1:8080/login/oauth2/code/felord-oidc,https://baidu.com","scopes": "openid,message.read,message.write","client_settings": "{\"@class\":\"java.util.Collections$UnmodifiableMap\",\"settings.client.require-proof-key\":false,\"settings.client.require-authorization-consent\":true}","token_settings": "{\"@class\":\"java.util.Collections$UnmodifiableMap\",\"settings.token.reuse-refresh-tokens\":true,\"settings.token.id-token-signature-algorithm\":[\"org.springframework.security.oauth2.jose.jws.SignatureAlgorithm\",\"RS256\"],\"settings.token.access-token-time-to-live\":[\"java.time.Duration\",300.000000000],\"settings.token.refresh-token-time-to-live\":[\"java.time.Duration\",3600.000000000]}"}

❝

注意上面的配置和你OAuth2.0客户端应用的配置息息相关。

既然持久化了，那自然需要操作该表的JDBC服务接口了，这个接口为RegisteredClientRepository。我们需要声明一个实现为Spring Bean，这里选择基于JDBC的实现：

@Beanpublic RegisteredClientRepository registeredClientRepository(JdbcTemplate jdbcTemplate) {return new JdbcRegisteredClientRepository(jdbcTemplate);}

别忘记调用save(RegisteredClient)方法把需要注册的客户端信息持久化。

❝

该实现依赖spring-boot-starter-jdbc类库，你也可以闲得慌使用Mybatis进行实现。

OAuth2授权信息持久化

记录授权的资源拥有者（Resource Owner）对某个客户端的某次授权记录。对应的Java类为OAuth2Authorization。下面是定义脚本:

CREATE TABLE oauth2_authorization
(id                            varchar(100)  NOT NULL,registered_client_id          varchar(100)  NOT NULL,principal_name                varchar(200)  NOT NULL,authorization_grant_type      varchar(100)  NOT NULL,attributes                    varchar(4000) NULL,state                         varchar(500)  NULL,authorization_code_value      blob          NULL,`authorization_code_issued_at`  timestamp     NULL,authorization_code_expires_at timestamp     NULL,authorization_code_metadata   varchar(2000) NULL,access_token_value            blob          NULL,access_token_issued_at        timestamp     NULL,access_token_expires_at       timestamp     NULL,access_token_metadata         varchar(2000) NULL,access_token_type             varchar(100)  NULL,access_token_scopes           varchar(1000) NULL,oidc_id_token_value           blob          NULL,oidc_id_token_issued_at       timestamp     NULL,oidc_id_token_expires_at      timestamp     NULL,oidc_id_token_metadata        varchar(2000) NULL,refresh_token_value           blob          NULL,refresh_token_issued_at       timestamp     NULL,refresh_token_expires_at      timestamp     NULL,refresh_token_metadata        varchar(2000) NULL,PRIMARY KEY (id)
);

❝

这里的机制目前还没有研究，先挖个坑。

同样它也需要一个持久化服务接口OAuth2AuthorizationService并注入Spring IoC：

/*** 管理OAuth2授权信息服务** @param jdbcTemplate               the jdbc template* @param registeredClientRepository the registered client repository* @return the o auth 2 authorization service*/
@Bean
public OAuth2AuthorizationService authorizationService(JdbcTemplate jdbcTemplate,RegisteredClientRepository registeredClientRepository) {return new JdbcOAuth2AuthorizationService(jdbcTemplate, registeredClientRepository);
}

持久化到数据库的OAuth2Authorization用JSON表示为：

{"id": "aa2f6e7d-d9b9-4360-91ef-118cbb6d4b09","registered_client_id": "658cd010-4d8c-4824-a8c7-a86b642299af","principal_name": "felord","authorization_grant_type": "authorization_code","attributes": "{\"@class\":\"java.util.Collections$UnmodifiableMap\",\"org.springframework.security.oauth2.core.endpoint.OAuth2AuthorizationRequest\":{\"@class\":\"org.springframework.security.oauth2.core.endpoint.OAuth2AuthorizationRequest\",\"authorizationUri\":\"http://localhost:9000/oauth2/authorize\",\"authorizationGrantType\":{\"value\":\"authorization_code\"},\"responseType\":{\"value\":\"code\"},\"clientId\":\"felord-client\",\"redirectUri\":\"http://127.0.0.1:8080/foo/bar\",\"scopes\":[\"java.util.Collections$UnmodifiableSet\",[\"message.read\",\"message.write\"]],\"state\":\"9gTcVNXgV8Pn_Ron3bkFb6M92AYCodeWKoEd6xxaiUg=\",\"additionalParameters\":{\"@class\":\"java.util.Collections$UnmodifiableMap\"},\"authorizationRequestUri\":\"http://localhost:9000/oauth2/authorize?response_type=code&client_id=felord-client&scope=message.read%20message.write&state=9gTcVNXgV8Pn_Ron3bkFb6M92AYCodeWKoEd6xxaiUg%3D&redirect_uri=http://127.0.0.1:8080/foo/bar\",\"attributes\":{\"@class\":\"java.util.Collections$UnmodifiableMap\"}},\"java.security.Principal\":{\"@class\":\"org.springframework.security.authentication.UsernamePasswordAuthenticationToken\",\"authorities\":[\"java.util.Collections$UnmodifiableRandomAccessList\",[{\"@class\":\"org.springframework.security.core.authority.SimpleGrantedAuthority\",\"authority\":\"ROLE_USER\"}]],\"details\":{\"@class\":\"org.springframework.security.web.authentication.WebAuthenticationDetails\",\"remoteAddress\":\"0:0:0:0:0:0:0:1\",\"sessionId\":\"FD624F1AD55A2418CC9815A86AA32696\"},\"authenticated\":true,\"principal\":{\"@class\":\"org.springframework.security.core.userdetails.User\",\"password\":null,\"username\":\"felord\",\"authorities\":[\"java.util.Collections$UnmodifiableSet\",[{\"@class\":\"org.springframework.security.core.authority.SimpleGrantedAuthority\",\"authority\":\"ROLE_USER\"}]],\"accountNonExpired\":true,\"accountNonLocked\":true,\"credentialsNonExpired\":true,\"enabled\":true},\"credentials\":null},\"org.springframework.security.oauth2.server.authorization.OAuth2Authorization.AUTHORIZED_SCOPE\":[\"java.util.Collections$UnmodifiableSet\",[\"message.read\",\"message.write\"]]}","state": null,"authorization_code_value": "EZFxDcsKoaGtyqRTS0oNMg85EcVcyLdVssuD3SV-o0FvNXsSTRjTmCdu0ZPZnVIQ7K4TTSzrvLwBqoRXOigo_dWVNeqE44LjHHL_KtujM_Mxz8hLZgGhtfipvTdpWWR1","authorization_code_issued_at": "2021-11-11 18:44:45","authorization_code_expires_at": "2021-11-11 18:49:45","authorization_code_metadata": "{\"@class\":\"java.util.Collections$UnmodifiableMap\",\"metadata.token.invalidated\":true}","access_token_value": "eyJ4NXQjUzI1NiI6IlZGR1F4Q21nSEloX2dhRi13UGIxeEM5b0tBMXc1bGEwRUZtcXFQTXJxbXciLCJraWQiOiJmZWxvcmRjbiIsImFsZyI6IlJTMjU2In0.eyJzdWIiOiJmZWxvcmQiLCJhdWQiOiJmZWxvcmQtY2xpZW50IiwibmJmIjoxNjM2NjI3NDg0LCJzY29wZSI6WyJtZXNzYWdlLnJlYWQiLCJtZXNzYWdlLndyaXRlIl0sImlzcyI6Imh0dHA6XC9cL2xvY2FsaG9zdDo5MDAwIiwiZXhwIjoxNjM2NjI3Nzg0LCJpYXQiOjE2MzY2Mjc0ODR9.CFzye9oIh8-ZMpyp9XoIXIQLnj2Sn17yZ9bgn7NYAbrp2hRq-Io_Se2SJpSEMa_Ce44aOGmcLTmIOILYUxlU08QCtHgr4UfCZttzroQhEn3Qui7fixBMprPYqxmu2KL5G_l3q5EWyh4G0ilHpByCBDeBGAl7FpaxSDlelnBfNGs9q6nJCs7aC40U_YPBRLoCBLVK1Y8t8kQvNu8NqCkS5D5DZAogpmlVg7jSIPz1UXVIh7iDTTQ1wJl6rZ1E87E0UroX4eSuYfMQ351y65IUlB14hvKhu03yDLTiVKtujOo3m0DAkJTbk3ZkFZEmDf4N3Yn-ktU7cyswQWa1bKf3og","access_token_issued_at": "2021-11-11 18:44:45","access_token_expires_at": "2021-11-11 18:49:45","access_token_metadata": "{\"@class\":\"java.util.Collections$UnmodifiableMap\",\"metadata.token.claims\":{\"@class\":\"java.util.Collections$UnmodifiableMap\",\"sub\":\"felord\",\"aud\":[\"java.util.Collections$SingletonList\",[\"felord-client\"]],\"nbf\":[\"java.time.Instant\",1636627484.674000000],\"scope\":[\"java.util.Collections$UnmodifiableSet\",[\"message.read\",\"message.write\"]],\"iss\":[\"java.net.URL\",\"http://localhost:9000\"],\"exp\":[\"java.time.Instant\",1636627784.674000000],\"iat\":[\"java.time.Instant\",1636627484.674000000]},\"metadata.token.invalidated\":false}","access_token_type": "Bearer","access_token_scopes": "message.read,message.write","oidc_id_token_value": null,"oidc_id_token_issued_at": null,"oidc_id_token_expires_at": null,"oidc_id_token_metadata": null,"refresh_token_value": "hbD9dVMpu855FhDDOYapwsQSx8zO9iPX5LUZKeXWzUcbE2rgYRV-sgXl5vGwyByLNljcqVyK9Pgquzbcoe6dkt0_yPQPJfxLY8ezEQ-QREBjxNYqecd6OI9SHMQkBObG","refresh_token_issued_at": "2021-11-11 18:44:45","refresh_token_expires_at": "2021-11-11 19:44:45","refresh_token_metadata": "{\"@class\":\"java.util.Collections$UnmodifiableMap\",\"metadata.token.invalidated\":false}"}

❝

存储的东西还是比较全的，甚至把Java类都序列化了。

确认授权持久化

资源拥有者（Resource Owner）对授权的确认信息OAuth2AuthorizationConsent的持久化，这个比较简单。下面是定义脚本:

CREATE TABLE oauth2_authorization_consent
(registered_client_id varchar(100)  NOT NULL,principal_name       varchar(200)  NOT NULL,authorities          varchar(1000) NOT NULL,PRIMARY KEY (registered_client_id, principal_name)
);

对应的持久化服务接口为OAuth2AuthorizationConsentService，也要注入Spring IoC:

@Bean
public OAuth2AuthorizationConsentService authorizationConsentService(JdbcTemplate jdbcTemplate, RegisteredClientRepository registeredClientRepository) {return new JdbcOAuth2AuthorizationConsentService(jdbcTemplate, registeredClientRepository);
}

持久化到数据库的OAuth2AuthorizationConsent用JSON表示为：

{"registered_client_id": "658cd010-4d8c-4824-a8c7-a86b642299af","principal_name": "felord","authorities": "SCOPE_message.read,SCOPE_message.write"}

JWK

JWK全称JSON Web Key，是一个将加密的密钥用JSON对象描述的规范，和JWT一样是JOSE规范的重要组成部分。规范的详细定义可参考JWK文档。JWK参考示例：

{"keys": [{"kty": "RSA","x5t#S256": "VFGQxCmgHIh_gaF-wPb1xC9oKA1w5la0EFmqqPMrqmw","e": "AQAB","kid": "felordcn","x5c": [

}

JWK的意义在于生成JWT和提供JWK端点给OAuth2.0资源服务器解码校验JWT。

公私钥

JWK会涉及到加密算法，这里使用RSASHA256算法来作为加密算法，并通过Keytool工具来生成.jks公私钥证书文件。当然你也可以通过openssl来生成pkcs12格式的证书。在Spring Security实战干货中已经对生成的方法进行了说明，这里不再赘述。

JWKSource

由于Spring Security的JOSE实现依赖的是nimbus-jose-jwt，所以这里只需要我们实现JWKSource <C extends SecurityContext>并注入Spring IoC即可。相关代码如下：

/*** 加载JWK资源** @return the jwk source*/@SneakyThrows@Beanpublic JWKSource<SecurityContext> jwkSource() {//TODO 这里优化到配置// 证书的路径String path = "felordcn.jks";// 证书别名String alias = "felordcn";// keystore 密码String pass = "123456";ClassPathResource resource = new ClassPathResource(path);KeyStore jks = KeyStore.getInstance("jks");
//        KeyStore pkcs12 = KeyStore.getInstance("pkcs12");char[] pin = pass.toCharArray();jks.load(resource.getInputStream(), pin);RSAKey rsaKey = RSAKey.load(jks, alias, pin);JWKSet jwkSet = new JWKSet(rsaKey);return (jwkSelector, securityContext) -> jwkSelector.select(jwkSet);}

授权服务器元信息配置

客户端信息RegisteredClient包含了Token的配置项TokenSettings和客户端配置项ClientSettings。授权服务器本身也提供了一个配置工具来配置其元信息，大多数我们都使用默认配置即可，唯一需要配置的其实只有授权服务器的地址issuer，在DEMO中虽然我使用localhost:9000了issuer没有什么问题，但是在生产中这个地方应该配置为域名。

/*** 配置 OAuth2.0 provider元信息** @return the provider settings*/@Beanpublic ProviderSettings providerSettings(@Value("${server.port}") Integer port) {//TODO 生产应该使用域名return ProviderSettings.builder().issuer("http://localhost:" + port).build();}

❝

你可以修改本地的hosts文件试试用域名。

到这里Spring Authorization Server的配置就完成了，但是整个授权服务器的配置还没有完成。

授权服务器安全配置

上面是授权服务器本身的配置，授权服务器本身的安全配置是另外一条过滤器链承担的，我们也要对它进行一些配置，都是常规的Spring Security配置，这里给一个简单的配置，也是DEMO中的配置：

@EnableWebSecurity(debug = true)
public class DefaultSecurityConfig {// @formatter:off@BeanSecurityFilterChain defaultSecurityFilterChain(HttpSecurity http) throws Exception {http.authorizeRequests(authorizeRequests ->authorizeRequests.anyRequest().authenticated()).formLogin();return http.build();}// @formatter:on/*** 在内存中抽象一个Spring Security安全用户{@link User}，同时该用户也是Resource Owner;* 实际开发中需要持久化到数据库。** @return the user details service*/
// @formatter:off@BeanUserDetailsService users() {UserDetails user = User.builder().username("felord").password("password").passwordEncoder(PasswordEncoderFactories.createDelegatingPasswordEncoder()::encode).roles("USER").build();return new InMemoryUserDetailsManager(user);}// @formatter:on/*** 开放一些端点的访问控制。** 如果你使用了一些依赖这些端点的程序，比如Consul健康检查；* 打开H2数据库web控制台访问控制，方便你查看数据具体看配置文件说明。** @return the web security customizer*/@BeanWebSecurityCustomizer webSecurityCustomizer() {return web -> web.ignoring().antMatchers("/actuator/health","/h2-console/**");}
}

到这里一个基于Spring Authorization Server的授权服务器就搭建好了。下一篇我们将实现OAuth2.0的登录功能，敬请期待。

解惑

❝

为什么一个项目配置了两个甚至多个SecurityFilterChain?

之所以有两个SecurityFilterChain是因为程序设计要保证职责单一，无论是底层架构还是业务代码，为此HttpSecurity被以基于原型（prototype）的Spring Bean注入Spring IoC。针对本应用中的两条过滤器链，分别是授权服务器的过滤器链和应用安全的过滤器链，它们之间其实互相没有太多联系。
